Data	Recommendation
MySQL	Full backup plus incremental or binlog backup.
Redis	Enable persistence according to deployment policy.
Uploaded files	Back up local storage or OSS bucket policies.
Time-series data	Back up according to retention and business value.
Configuration	Keep deployment scripts, environment files, Nginx, broker, and ZLM configs versioned.
